Risk from blood draw site touching railing on a bus?


Hi, I have a risk assessment question.

Today I had my routine STI testing and took the bandage off and the blood draw puncture wound was dry. I got on the bus and absentmindedly wrapped my arm around the vertical rail for support. I probably didn’t touch the blood draw site to the rail, but I could have. Then I realized the site was close to the rail and had a minor anxious panic and stopped at shoppers drug mart for hand sanitizer and scrubbed it, then it bled just a bit from the sanitizer scrub. The bus rail didn’t appear to have had any obvious blood on it after I took my arm off it. When I was touching the rail the venipuncture site was dry and not bleeding.

What, if any, is the risk of transmission of hiv/hcv?

I know this seems like a trivial question, but I experience a lot of anxiety and am looking for some support.



Thank you for your inquiry. From what we gather from the question, you are asking about the potential risk of acquiring HIV from your closed wound coming into contact with a bus railing. From the information given, this scenario is considered no risk (transmission of HIV is not possible in the given scenario), because the bus railing is exposed to oxygen, and oxygen renders most HIV inactive within 1-2 hours.

Recommendation: No need for HIV test with the scenario provided, refer to a physician for other health-related questions
